100% PROUDLY MADE IN THE USA | 9 Molten Metal Launder Systems The most technically advanced way to deliver molten aluminum from melting furnaces to holders and die casting machines is in a heated launder system. A launder minimizes turbulence and oxides in the molten metal and because the metal flows in a quiet stream to the holding furnace, it eliminates transfer labor and monorails, fork trucks, and bull ladles. It automatically delivers the exact amount of metal you need — on-time and at temperature. Launder systems aren’t the answer for everyone. They must be carefully considered because they can reduce the flexibility of your plant layout. But they can be very cost-effective in the right application. We have both the technology and the creative designs to meet your needs. Our launders are well sealed, highly insulated and easy to clean. ADVANTAGES: • Metal quality — ensured through minimized turbulence and oxides. • Highly insulated — to maintain temperature. • Easy to clean. • Reduces the need for transfer equipment. • Reduces manpower and fork lift maintenance. • Save ½ of 1% in metal melt loss caused by turbulent transfers into and from transfer ladles. FOR: This versatile launder system meets the needs of a variety of metal casters, high and low pressure die casters, and permanent mold, sand, investment and lost foam foundries around the world. Dry Hearth Furnaces We design Dry Hearth furnaces to melt aluminum ingot and large billet; no gassing or contamination by the lining means that metal purity remains high. Impurities and the oxide skin stay on the hearth as only molten aluminum enters the hold zone. CASE STUDY: • Low fuel consumption — a modest 2.0 CF of gas per pound (504 kcal/0.4536 kg) of melted aluminum, thanks to the highly efficient radiant roof; this number drops even further with high momentum burners. A twozone control offers the closest temperature control possible. • Easy to Clean — charge and clean-out doors are tangent with the side walls for quick cleaning access. A double hinged or full width clean-out door provides easy and complete access to the hold zone. FOR: This versatile furnace meets the needs of a variety of metal casters, high and low pressure die casters, and permanent mold, sand, investment and lost foam foundries around the world.
